IiPropati zokuNyetshezwa kunye nokuSila kweNano Silicon Carbide

Nano Silicon carbide powder(HW-D507) iveliswa ngokunyibilikisa isanti yequartz, i-petroleum coke (okanye i-coke coke), kunye neenkuni zokhuni njengezinto eziluhlaza ngokusebenzisa ubushushu obuphezulu kwiziko lokumelana. I-silicon carbide ikhona kwindalo njengeminerali enqabileyo- ebizwa ngokuba yi-moissanite. Kwitekhnoloji ephezulu ye-refractory imathiriyeli ekrwada enje nge-C, N, B kunye nezinye i-non-oxide, i-silicon carbide yeyona isetyenziswa kakhulu kwaye yeyona inoqoqosho.

β-SiC umguboineepropati ezinjengozinzo oluphezulu lweekhemikhali, ubunzima obuphezulu, i-conductivity ephezulu ye-thermal, i-coefficient yokwandisa i-thermal ephantsi kunye nokunye. Ke ngoko, inemisebenzi ebalaseleyo efana ne-anti-abrasion, ukumelana nobushushu obuphezulu kunye nokumelana nobushushu bobushushu. I-silicon carbide ingenziwa ibe ngumgubo otyumkileyo okanye iintloko zokusila ukwenzela ukuchaneka okuphezulu kunye nokupholisa izinto ezifana neentsimbi, iiseramics, iglasi kunye neeplastiki. Xa kuthelekiswa nezixhobo ze-abrasive zendabuko, i-SiC inokumelana nokunxiba okuphezulu, ubunzima kunye nokuzinza kwe-thermal, enokuphucula ngokufanelekileyo ukuchaneka kokucubungula kunye nokusebenza kakuhle. Ukongeza, inokumelana neekhemikhali ezigqwesileyo kunye nokuzinza kobushushu obuphezulu, ngoko inoluhlu olubanzi lwamathemba okusebenza kwiinkalo ezahlukeneyo.

I-SiC ingasetyenziselwa ukulungiselela izinto zokupolisha, ezinoluhlu olubanzi lwezicelo kubunjineli bomatshini, izixhobo zombane, izixhobo zokukhanya kunye nezinye iinkalo. Le nto yokupholisa ineempawu ezibalaseleyo ezifana nobunzima obuphezulu, ukumelana nokunxiba okuphezulu kunye nokuzinza okuphezulu kweekhemikhali, ezinokufezekisa umgangatho ophezulu wokupolisha kunye nokusebenza kokusila. Okwangoku, izinto eziphambili zokugaya kunye nokupholisha yidayimane kwimarike, kwaye ixabiso layo ngamashumi okanye namakhulu amaxesha e-β-Sic. Nangona kunjalo, impembelelo yokusila ye-β-Sic kwiindawo ezininzi ayikho ngaphantsi kwedayimane. Xa kuthelekiswa namanye ama-abrasives anomlinganiselo ofanayo we-particle, i-β-Sic ineyona ndlela iphezulu yokusebenza kakuhle kunye nokusebenza kweendleko.

Njengomathiriyeli wokupolisha kunye nokusila, i-nano silicon carbide ikwanayo ne-coefficient ephantsi ye-friction kunye nepropathi egqwesileyo ye-optical, esetyenziswa ngokubanzi kwi-microelectronic processing kunye nokwenza izixhobo ze-optoelectronic. I-Nano silicon carbide polishing kunye nezixhobo zokusila zinokufikelela kwizakhono eziphezulu kakhulu zokupholisa, ngelixa ulawula kwaye unciphisa uburhabaxa bomphezulu kunye ne-morphology, ukuphucula umgangatho wezinto eziphathekayo kunye nokusebenza kwemveliso.

Kwizixhobo zedayimani ezisekelwe kwi-resin, i-nano silicon carbide yinto eyongezelelweyo ebalulekileyo enokuphucula ngokufanelekileyo ukuxhathisa ukunxiba, ukusika kunye nokusebenza kokupolisha kwezixhobo zedayimani ezisekelwe kwi-resin. Okwangoku, ubungakanani obuncinci kunye nokusasazwa okuhle kwe-SiC kunokuphucula ukusebenza kwezixhobo zedayimane esekwe kwintlaka ngokuxuba kakuhle kunye nezixhobo ezisekwe kwintlaka. Inkqubo ye-nano SiC yokuvelisa izixhobo zedayimani ezisekelwe kwi-resin ilula kwaye ilula. Okokuqala, i-nano SiC powder ixutywe kunye ne-resin powder kwi-resin eqingiweyo, kwaye emva koko ishushu kwaye icinezele ngokubumba, enokuphelisa ngokufanelekileyo ukusabalalisa okungalinganiyo kwamasuntswana edayimane ngokusebenzisa ipropati efanayo yokusabalalisa i-nanoparticles ye-SiC, ngaloo ndlela iphucula kakhulu amandla kunye ukuqina kwezixhobo kunye nokwandisa ubomi babo benkonzo.

Ukongeza ekwenzeni izixhobo zedayimani esekwe kwintlaka,i-silicon carbide nanoparticlesingasetyenziselwa ukuvelisa i-abrasives ezahlukeneyo kunye nezixhobo zokusebenza, ezifana namavili okugaya, i-sandpaper, izinto zokupholisa, njl. Ithemba lesicelo se-nano silicon carbide libanzi kakhulu. Ngomkhwa okhulayo wamashishini ahlukeneyo okusebenzisa ukusebenza okuphezulu kunye nezixhobo eziphezulu zokusetyenzwa kunye ne-abrasives, i-nano silicon carbide ngokuqinisekileyo iya kuvelisa usetyenziso olubanzi ngakumbi kula macandelo.

Ukuqukumbela, i-nano silicon carbide powder inethemba elibanzi lesicelo njengemathiriyeli yomgangatho ophezulu wokupolisha. Ngenkqubela phambili eqhubekayo yesayensi kunye neteknoloji, i-nano silicon carbide kunye nezixhobo zedayimani ezisekelwe kwi-resin ziya kuphuculwa ngokuqhubekayo kwaye ziphuculwe kwiinkalo ezibanzi.

I-Hongwu Nano ngumvelisi oqeqeshiweyo we-nano yomgubo wentsimbi exabisekileyo kunye nee-oxides zazo, ezinomgangatho wemveliso othembekileyo nozinzileyo kunye nexabiso elihle. IHongwu Nano ibonelela ngeSiC nanopowder. Wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe kratya.
